Specification of Letters Patent. Patented A11 20, 1918.

Application filed August 3, 1917. Serial No. 184,281.

To all whom it may concern:

Be it known that I, HAL RIVIERE, a citizen of the United States, and a resident of Columbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in Bobbin-'Holders and Tension Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to'which it appertains to make and use the same.

This invention relates to improvementsin bobbin holders and tension devices, and more particularly to such as may be employed on machines for spooling filling wind from bobbins to spools,the object of the invention being to provide a device of the character specified which shall be simple in construction; which will require no adjustment in order to spool difierent numbers of yarn which will permit any desired tension; and which will be normally retained in proper operative position, but which will operate automatically to cause the guide and tension device to drop out of line with the bobbin when the latter becomes exhausted, thereby permitting the ready removal of an empty bobbin and the placing of a filled one in position.

With these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure l is a view showing the application of my improvements; Fig. 2 is a view showing the positions which the parts will assume when the yarn has become exhausted from the bobbin, and Fig. 3 is a view showing a modification.

1 represents abracket comprising an enlarged portion 2 having an opening 3 whereby the bracket may be secured to a bar 4 by means of a set screw 5,said bracket also comprising arms 6 and 7 disposed at right angles to each other. A spindle 8 projects from the arm 7 and is disposed at right angles thereto for the reception of a bobbin 9, which latter is preferably held from rotation by frictional engagement with said spindle. V

The arm 6 of the bracket is provided near its free end with lugs 10, to which a weighted arm 11 is pivotally attached a comparatively short distance from its upper end. To

the upper end of this weighted arm, a. rod or wire 12 is secured and bent to provide a lateral arm 13 adapted to project across the end of the spindle and the bobbin thereon, an appreciable distance removed from the free ends of the same. bent to form two loops 14 and 15,the latter being located at the free end of said arm and the former being located at an intermediate position. 1

The bracket 1 will be so secured to the bar 4. that it will be; disposed at an; angleof approximately thirty degrees above the horizontal, or sufficient to be in proper relation to the spooler.

The weighted arm 11 is such that it will The wire arm 13 is,

approximately counterbalance the rod or wire 12-13.

When a filled bobbin has been placed on the spindle 8 as shown in Fig. 1, the oper-' ator will thread the yarn through the loop 14, then wrap it once or several times around the arm 13 between the loops 14 and 15 according to the amount of tension which may be desired, and then the yarn will be passed through the loop 15, and finally, the yarn will be led through any suitable guide to the spool on the spooler (not shown). The friction of the yarn as it passes about the tension arm and its loops will hold the same in such position that theloop 14 will be retained in proper alinement with the bobbin so that the yarn may be readily unwound. When the yarn shall have become exhausted from the bobbin, the counterweighted guide and tension devices will drop back automatically,-as indicated in Fig. 2, so that the empty bobbin may be readily removed and a filled bobbin placed in position on the spindle. In the form of the invention shown in Fig. 8, the lower end of the rod or wire 12 is shown rigidly connected with the arm 6 and from the loop or coil 14 of the wire arm 13, said wire arm is extended forwardly and offset as shown at 16 and to the portion 16 a whirl 17 is secured for the passage of the thread. The wire members 12, 13', 16 may be pressed ba'ckto faciliout departing from the spirit thereof or limiting its scope and hence I do not- Wish to restrict myself to the precise details herein set forth.

Having fully described my invention What I claim as new and desire tosecure by Letters-Patent, is

1. The combination of a bracket comprising two arms and a spindle secured to one arm and approximately parallel With the other, a Weighted arm pivotally secured to said other arm, rod or Wire secured to the Weighted arm and having a lateral member adapted to be held by the thread over the free end of the spindle and to move out of the plane of the spindle when. the thread is exhausted, said lateral member having loops for the passage of the thread, one of said loops adapted to be operatively'disposed in line with the spindle when the loop is under tension of the thread passing through the same.

2. The combination of a bracket composed of two substantially right angle arms, a spindle secured to one arm and approximately parallel to the other, and a flexible Wire bent to form tWo members disposedat an angle to each other, one of said Wiremembers being attached to said other arm of the bracket and the other Wire member disposed 3 ing Witnesses.
